Definitions

  • the invention relates to a medical imaging system comprising a frame accommodating an imaging device and an examination volume, the system further comprising a patient support member, a first displacement device for displacing the patient support member relative to the frame in a first horizontal direction into and out of the examination volume, and a second displacement device for displacing the patient support member relative to the frame in a second horizontal direction transverse to the first horizontal direction, the patient support member being provided on a mobile carrier which comprises a first docking member by means of which the carrier can be docked to a second docking member provided on the frame.
  • An example of a known medical imaging system is a magnetic resonance imaging system by means of which images can be made of the entrails of a patient using nuclear magnetic resonance methods.
  • the imaging device of the known magnetic resonance imaging system comprises an electrical coil system for generating a varying magnetic field and radio-frequency signals in the examination volume, in which the patient is to be placed, and for receiving radio-frequency signals generated by the patient's body in response to the radio-frequency signals generated by the coil system.
  • the patient support member is a horizontal bed, and the mobile carrier, on which the patient support member is provided, is a trolley.
  • the patient support member is provided on the mobile carrier, the patient support member with the patient lying on it can be moved from the imaging system to, for example, a preparation room or to another medical examination or treatment device.
  • the mobile carrier can be mechanically coupled to the frame, so that the patient support member provided on the mobile carrier is brought in a stable position relative to the frame and the imaging device.
  • the docking members also comprise electrical connections between the mobile carrier and the imaging device, so that a battery, which is provided on the mobile carrier for feeding electrical systems of the mobile carrier, can be charged and information about the patient, stored in an electrical memory of the mobile carrier, can be exchanged between the mobile carrier and the imaging device.
  • the first displacement device is provided in the mobile carrier.
  • the patient support member with the patient lying on it can be displaced by the first displacement device relative to the mobile carrier and relative to the frame, to which the mobile carrier is docked, in the first horizontal direction, so that the patient is moved into the examination volume and, after the examination, out of the examination volume.
  • the second displacement device is also provided in the mobile carrier, so that, in the docked condition of the mobile carrier, the patient can also be moved relative to the frame and the imaging device in the second horizontal direction. This is often necessary to bring the part of the patient's body to be examined in a correct position relative to the imaging device.
  • a drawback of the known medical imaging system is that, in particular in the case of diverent patients, the center of gravity of the patient support member and the patient lying on it comes close to the wheels of the mobile carrier, seen in the second horizontal direction, when the patient support member with the patient lying on it is displaced relative to the mobile carrier in the second horizontal direction, whereby the stability of the mobile carrier strongly decreases and the mobile carrier could fall over. As a result, the distance over which the patient support member can be displaced in the second direction is limited.
  • An object of the invention is to provide a medical imaging system of the kind mentioned in the opening paragraph which does not have the drawback of the known medical imaging system.
  • a medical imaging system is characterized in that the second displacement device is provided on the frame for displacing the second docking member relative to the frame in the second horizontal direction.
  • displacements of the patient support member relative to the frame in the second horizontal direction are generated in the docked condition of the mobile carrier by displacing the second docking member, together with the mobile carrier and the patient support member mechanically coupled thereto, in the second horizontal direction by means of the second displacement device.
  • the patient support member does not need to be displaced relative to the mobile carrier in the second horizontal direction and can be mounted or maintained in a fixed stable position relative to the mobile carrier, seen in the second horizontal direction.
  • the patient support member can be displaced in a stable manner in the second horizontal direction over relatively large distances.
  • An additional advantage of a medical imaging system according to the invention in particular of such systems which comprise at least two mobile carriers each with a separate patient support member which can alternately be docked to the frame, is that the mobile carrier has a relatively simple structure, because the mobile carrier does not accommodate the second displacement device.
  • a particular embodiment of a medical imaging system according to the invention is characterized in that the carrier is mobile by means of rolling members.
  • the rolling members provide a stable support for the mobile carrier and the patient support member provided thereon when forces are exerted on the mobile carrier via the docking members to displace the mobile carrier in the second horizontal direction.
  • a further embodiment of a medical imaging system according to the invention is characterized in that the system is a magnetic resonance imaging system and the frame comprises a lower coil system housing and an upper coil system housing between which the examination volume is present, the second docking member and the second displacement device being provided in the lower coil system housing.
  • the medical imaging system is a magnetic resonance system of the so-called open type, wherein the examination volume is bounded in the vertical direction by the lower coil system housing and the upper coil system housing and wherein the examination volume is open in the major part of its horizontal plane.
  • the invention is particularly suitable for use in a magnetic resonance imaging device of the open type, because the open examination volume allows relatively large displacements of the patient within the examination volume in the second horizontal direction.
  • the patient's body can be brought in a more correct position relative to the imaging device than in a magnetic resonance imaging device of the so-called closed type having a relatively narrow cylindrical examination volume.
  • the second docking member and the second displacement device are provided in the lower coil system housing, because the lower coil system is relatively close to the mobile carrier.
  • a yet further embodiment of a medical imaging system is characterized in that the system comprises a guide member which is present in the examination volume, is mounted to the second docking member, and extends in the first horizontal direction for guiding and supporting the patient support member in the examination volume.
  • the guide member Since the guide member is mounted to the second docking member, the guide member is displaced by the second docking member in the second horizontal direction together with the mobile carrier docked to the second docking member, so that the guide member is always maintained in a correct position relative to the mobile carrier, i.e.
  • the patient support member can be docked to the second docking member and subsequently be displaced into the examination volume in each possible position of the second docking member, seen in the second horizontal direction, and the patient support member can also be displaced out of the examination volume and subsequently be undocked from the second docking member in each possible position of the patient support member, seen in the second horizontal direction.
  • a particular embodiment of a medical imaging system according to the invention is characterized in that the guide member is provided on a bridge-shaped further carrier which bridges over the lower coil system housing and comprises a first leg, which is mounted to and supported by the second docking member, and a second leg, which is supported by rolling members at a side of the lower coil system housing opposite to a side where the second docking member is present.
  • the bridge-shaped further carrier provides a practical and stable support for the guide member in the examination volume above the lower coil system housing.
  • a further embodiment of a medical imaging system according to the invention is characterized in that the guide member is provided on a bridge-shaped further carrier which spans over the lower coil system housing and comprises a first leg, which is mounted to and supported by the second docking member, and a second leg, which is present at a side of the lower coil system housing opposite to a side where the second docking member is present and which is connected to the first leg by means of a connecting member extending underneath the lower coil system housing.
  • the connecting member strongly improves the rigidity of the bridge-shaped further carrier.
  • FIG. 1 shows a medical imaging system according to the invention
  • Fig. 2 shows the medical imaging system of Fig. 1 with a patient support member of the system being present in an examination volume of the system
  • Fig. 3 shows a front view of the medical imaging system of Fig. 1

  • Fig. 5 schematically shows a bridge-shaped carrier of the medical imaging system of Fig. 1
  • Fig. 6 schematically shows a bridge-shaped carrier of an alternative embodiment of a medical imaging system according to the invention.
  • the medical imaging system according to the invention shown in Fig. 1 is a magnetic resonance imaging system of the so-called open type by means of which images can be made of the entrails of a patient using a nuclear magnetic resonance method.
  • the medical imaging system comprises a frame 1 having a lower coil system housing 3 and an upper coil system housing 5 which accommodate an electrical coil system.
  • the coil system which is not shown in Fig. 1, is a part of an imaging device of the medical imaging system, which is also not shown in Fig. 1 and which can be of a kind which is known per se.
  • an examination volume 7 is present in which the patient is to be placed.
  • the examination volume 7 is bounded in the vertical direction Z by the lower coil system housing 3 and the upper coil system housing 5.
  • the lower coil system housing 3 and the upper coil system housing 5 are interconnected by means of two vertical columns 9, 11 of the frame 1, which have a relatively small cross- section, so that the examination volume 7 is open in the major part of its horizontal plane.
  • the coil system generates a varying magnetic field and radio-frequency signals in the examination volume 7.
  • the patient's body In response to the radio-frequency signals generated by the coil system, the patient's body generates radio-frequency signals, which are received by the coil system and are processed into an image of the patient's body by the imaging device.
  • the medical imaging system further comprises a patient support member 13, in particular a horizontal bed, which is provided on a mobile carrier 15, in particular a trolley which is mobile by means of rolling members 17.
  • the mobile carrier 15 is provided with a first docking member 19 by means of which the mobile carrier 15 can be docked to a second docking member 21 which is provided on the frame 1, in particular at a front side 23 of the lower coil system housing 3. Since the patient support member 13 is provided on the mobile carrier 15, the patient support member 13 with the patient lying on it can be moved from the medical imaging system to, for example, a separate preparation room, where the patient is prepared before the examination, or to another medical examination or treatment device to undergo a subsequent examination or treatment.
  • the medical imaging system comprises at least two mobile carriers 15 each with a separate patient support member 13.
  • a second patient can be prepared during the examination of a first patient and, after the examination of the first patient, the mobile carrier 15 with the patient support member 13 carrying the first patient can be undocked from and moved away from the medical imaging system, while the mobile carrier 15 with the patient support member 13 carrying the second patient can immediately be moved to and docked to the medical imaging system.
  • the medical imaging system can efficiently be used.
  • the mobile carrier 15 can be mechanically coupled to and uncoupled from the lower coil system housing 3, so that the patient support member 13 provided on the mobile carrier 15 can be brought into a pre-defined stable position relative to the frame 1 and the imaging device.
  • the first docking member 19 and the second docking member 21 can be provided with conventional mechanical coupling means which will not be described further.
  • the first docking member 19 and the second docking member 21 also comprise electrical connections between the mobile carrier 15 and the imaging device.
  • the mobile carrier 15 or the patient support member 13 can be provided, for example, with an electrical memory in which information about the patient can be stored, which information can be exchanged between said memory and the imaging device via said electrical connections.
  • a battery which may be provided on the mobile carrier 15 for feeding electrical systems of the mobile carrier 15 or the patient support member 13, can be charged via said electrical connections.
  • the patient support member 13 with the patient lying on it can be displaced relative to the mobile carrier 15 and the frame 1 in a first horizontal direction X from a first position shown in Fig. 1, in which the patient support member 13 is fully supported by the mobile carrier 15, to a second position shown in Fig. 2, in which the patient support member 13 is present in the examination volume 7.
  • the mobile carrier 15 is provided with a first guide member 25 which, in the docked condition of the mobile carrier 15, extends in the first horizontal direction X and co-operates with guide elements 27 provided on the patient support member 13.
  • the frame 1 is provided with a second guide member 29, which is present in the examination volume 7 and extends in the first horizontal direction X and which, in the docked condition of the mobile carrier 15, is in line with the first guide member 25.
  • the mobile carrier 15 further comprises a first displacement device for displacing the patient support member 13 along the first guide member 25 and along the second guide member 29 into the examination volume 7 and, after the examination of the patient, out of the examination volume 7 again.
  • the first displacement device may be of a conventional kind and may be provided, for example, with an elongate push-pull member 31, shown in Fig. 2, which is fastened to the patient support member 13 and is driven by an electrical motor provided in the mobile carrier 15.
  • the guiding and supporting functions of the first guide member 25 of the mobile carrier 15 are taken over by the second guide member 29 and, when the patient support member 13 is displaced out of the examination volume 7, the guiding and supporting functions of the second guide member 29 are taken over again by the first guide member 25.
  • the medical imaging system further comprises a second displacement device 33 by means of which the patient support member 13, in the docked condition of the mobile carrier 15, can be displaced relative to the frame 1 and the imaging device in a second horizontal direction Y transverse to the first horizontal direction X.
  • a second displacement device 33 By displacing the patient relative to the imaging device in the second horizontal direction Y, the portion of the patient's body to be examined can be brought into a correct position relative to the imaging device.
  • relatively large displacements of the patient support member 13 in the second horizontal direction Y are possible as a result of the fact that the examination volume 7 is open in the major part of its horizontal plane.
  • the patient's body can be brought into a more correct position relative to the imaging device than in a magnetic resonance imaging device of the so-called closed type, which has a relatively narrow cylindrical examination volume.
  • the second displacement device 33 is provided on the frame 1, in particular in the lower coil system housing 3, for displacing the second docking member 21 relative to the frame 1 in the second horizontal direction Y.

  • a first end portion 43 and a second end portion 45 of the spindle 41 are journalled respectively in a first bearing bush 47 and in a second bearing bush 49, which are both mounted to the frame member 37.
  • a third bearing bush 51 which comprises an internal screw thread for co-operation with the screw-thread of the spindle 41, is mounted to the second docking member 21.
  • the second displacement device 33 further comprises an electrical motor 53 mounted to the frame member 37 for driving a gear wheel 55 which is mounted to the first end portion 43 of the spindle 41. When the gear wheel 55 is driven by the motor 53, the second docking member 21 is displaced along the linear guide member 35 as a result of the co-operation between the screw-threads of the spindle 41 and of the third bearing bush 51.
  • the mobile carrier 15 does not need to be provided with an additional displacement device for displacing the patient support member 13 in the second horizontal direction Y relative to the mobile carrier 15, so that the patient support member 13 can be mounted and maintained, seen in the second horizontal direction Y, in a fixed central position relative to the mobile carrier 15.
  • the patient's center of gravity is always maintained, seen in the second horizontal direction Y, in a central position relative to the rolling members 17 during displacements of the patient support member 13 in the second horizontal direction Y, so that the patient support member 13 is displaced in a stable manner in the second horizontal direction Y relative to the frame 1.
  • the maximum distance over which the patient support member 13 can be displaced relative to the frame 1 in the second horizontal direction Y is not limited by the dimensions of the mobile carrier 15 in the second horizontal direction Y, but is determined by the length of the spindle 41, which can be such that the patient support member 13 can be displaced relative to the frame 1 in the Y-direction over the relatively large distance allowed by the dimensions of the examination volume 7.
  • the rolling members 17 provide a stable support for the mobile carrier 15 and the patient support member 13 during displacements of the mobile carrier 15 in the second horizontal direction Y by means of the second displacement device 33.
  • the stability of the mobile carrier 15 during displacements in the second horizontal direction Y is further improved by the fact that the first docking member 19 and the second docking member 21 are provided, to the extent possible, near the floor surface, i.e. to the extent possible near the imaginary horizontal surface in which the rolling member 17 are situated.
  • mechanical moments resulting from the forces exerted on the mobile carrier 15 via the docking members 19 and 21 during displacements of the mobile carrier 15 by the second displacement device 33 and causing instability of the mobile carrier 15 are limited as much as possible.
  • the structure of the mobile carrier 15 is relatively simple. This is particularly advantageous in embodiments of a medical imaging system according to the invention which are provided with two or more than two mobile carriers 15, each with a separate patient support member 13, which can alternately be docked to the frame 1.
  • the bridge-shaped further carrier 57 which is separately shown in Fig. 5, comprises a first substantially vertical leg 59, which is situated at the front side 23 of the lower coil system housing 3 and comprises curved supporting members 61, and a second substantially vertical leg 63, which is situated at a back side of the lower coil system housing 3 opposite to the front side 23 and comprises curved supporting members 65.
  • a first end portion 67 and a second end portion 69 of the second guide member 29 are mounted to respectively the curved supporting members 61 and the curved supporting members 65.
  • the lower end portion of the first leg 59 is connected to the lower end portion of the second leg 63 by means of a horizontal plate-shaped connecting member 71 which extends underneath the lower coil system housing 3 in a gap-shaped opening 73, which is present between the lower coil system housing 3 and a foot 75 of the frame 1 as shown in Fig. 3.
  • the bridge- shaped further carrier 57 has a relatively high rigidity.
  • the first leg 59 is mounted to and supported by the second docking member 21, which is only schematically shown in Fig. 5.
  • the bridge-shaped further carrier 57 and the second guide member 29 are arranged in a fixed position relative to the second docking member 21, so that the second guide member 29 is displaced by the second displacement device 33 in the second horizontal direction Y together with the mobile carrier 15 and the patient support member 13 docked to the second docking member 21.
  • the second guide member 29 is maintained in a correct position relative to the mobile carrier 15 during displacements of the mobile carrier 15 in the second horizontal direction Y, i.e. in a position wherein the second guide member 29 is in line with the first guide member 25 provided on the mobile carrier 15.
  • the first guide member 25 is always brought into a correct position in line with the second guide member 29, i.e. irrespective of the position of the second docking member 21 in the second horizontal direction Y, when the mobile carrier 15 is moved to the frame 1 and docked thereto. Consequently, the mobile carrier 15 can be docked to the second docking member 21 and the patient support member 13 can subsequently be displaced into the examination volume 7 in each possible position of the second docking member 21, seen in the second horizontal direction Y. Furthermore, the patient support member 13 can be displaced out of the examination volume 7 and the mobile carrier 15 can subsequently be undocked from the second docking member 21 in each possible position of the patient support member 13 in the examination volume 7, seen in the second horizontal direction Y.

  • the first leg 81 is mounted to and supported by the second docking member 21 , and the second leg 83 is supported and guided by rolling members 85 over a guiding surface 87, which extends in the second horizontal direction Y and is provided on the foot 75 of the frame 1.
  • the rolling members 85 may be guided over the floor surface.
  • the medical imaging system according to the invention described before is a magnetic resonance imaging system of the so-called open type. It is noted that the invention also includes magnetic resonance imaging systems of the so-called closed type having a relatively narrow cylindrical examination volume. Although such a narrow examination volume allows only limited displacements of the patient support member in the second horizontal direction Y, the invention is still advantageous for closed type systems having two or more than two mobile carriers, each with a separate patient support member, which can alternately be docked to the frame. It is further noted that the invention also includes medical imaging systems of a different kind than magnetic resonance imaging systems such as, for example, X-ray or CT imaging systems.
  • the invention also includes embodiments in which the second displacement device for displacing the second docking member 21 in the second horizontal direction Y is of a different kind than the displacement device 33 shown in Fig. 4.
  • the second displacement device may, for example, be provided with a toothed bar, mounted to the frame 1 , and a toothed wheel co-operating with the toothed bar and driven by an electric motor mounted to the second docking member 21.
  • the invention also includes embodiments in which the docking members 19 and 21 are positioned in a different vertical position than the vertical position close to the floor surface shown in Fig.l.
